百行代码入门Python

以下代码均采用Python 3.5.2编写。
建立一个名为HelloWorld.py的文件，当然名字无所谓，只要不是文字提及的其它文件名字即可，读懂以下代码方可轻松入门Python：

#Classclass Bird(object):    feather= True    reproduction="egg"    def chirp(self, sound):        print(sound)    def set_color(self,color):        self.color=color        return colorsummer = Bird()summer.chirp("jijijiji")print(summer.feather)print(summer.set_color("yellow"))#Magic Methodclass Bird2(object):    def __init__(self, sound):        self.sound=sound    def chirp(self):        print(self.sound)summer = Bird2("jiji")summer.chirp()#Inheritanceclass Chicken(Bird):    how_to_move = "walk"    edible=Trueclass Swan(Bird2):    how_to_move = "swim"    edible=False    def chirp(self):        super().chirp()        print("jijijiji")summer = Chicken()summer.chirp("ji")bird=Bird2("ji")bird.chirp()summer = Swan("ji")summer.chirp()#class listi = [1, 2, 3, 4, 9.0, "Good", -1, True, False, "Bye"]print(i.count(4))print(i.index(3))i.append(6)print(i)i.reverse()print(i)i.pop()print(i)i.remove(2)print(i)i.insert(0,9)print(i)i.clear()print(i)#iterexample_iter=iter([1,2,3,4])print(type(example_iter))print(example_iter.__next__())print(example_iter.__next__())for i in example_iter:    print(i, "example_iter in for")#generatordef gen():    a=100    yield a    a=a*8    yield a    yield 1000print(type(gen()))for i in gen():    print(i)#class Moduleimport timeprint(dir(time))from time import sleepsleep(1)print("Wake Up")from time import *sleep(1)print("Wake Up 2")time.sleep(1)print("Wake Up 3")
